Yeah. Extreme cold can do some funny things. Some times those sun dogs take on the appearance of two small suns, each about 15 degrees equidistant from the actual sun.
One of my most enduring memories from childhood is standing outside waiting for the bus at the end of our (rather long) driveway, just as the sun was coming up in January. Mornings of -40 were not uncommon (we never really knew how much lower than that it got, because mercury freezes solid at -40 and bursts the thermometer, so we always had a few extra on hand). Anyway the rising sun if it struck a tree just right would warm it up enough so that the tree would explode. Sounded just like a rifle shot. Didn't happen often but now and again when walking in the woods you'd see a tree that was split maybe 2/3 of the way up and know that that is what happened.
